      OBJECTIVES: To clarify the prevalence and severity of injuries and illnesses in university handball players. DESIGN: Prospective cohort study. SETTING: Survey-based online questionnaire. PARTICIPANTS: 231 university handball players (109 males and 122 females) over 38 weeks. MAIN OUTCOME MEASURES: Each participant completed the Japanese version of the Oslo Sports Trauma Research Center Questionnaire on Health Problems every Sunday. The main outcome measures were the average weekly prevalence of injuries and illnesses, duration, average weekly severity scores rated on a scale of 0-100 based on answers to four key questions, and cumulative severity scores. RESULTS: The average weekly prevalence was 27.4 % (95 % CI: 25.6-29.1 %) for injuries and 2.2 % (95 % CI: 1.6-2.8 %) for illnesses. Among injuries, traumatic injuries had higher average weekly severity scores (50.0 vs 32.0, p < 0.05) and cumulative severity scores per case (65.0 vs 42.0, p < 0.05) than overuse injuries. Conversely, overuse injuries lasted approximately 10 days longer than traumatic injuries (18 days vs 10 days, p < 0.05). Traumatic knee injuries and overuse shoulder injuries ranked the highest in prevalence, duration, and cumulative severity scores. CONCLUSIONS: We found that, although overuse injuries were less severe than traumatic injuries, they interfered with handball activities for extended periods.

      OBJECTIVES: This study aimed to examine injury surveillance practices in a variety of university sports teams and barriers and facilitators for injury data collection and utilisation. DESIGN: Cross-sectional study. SETTING: University sports teams in Japan. PARTICIPANTS: Medical, coaching, and other staff (non-medical/-coaching staff) of the university sports teams in Japan. MAIN OUTCOME MEASURES: The survey included 31 questions that examined the barriers and facilitators for injury data collection, and the type of data on injury and exposure collected. RESULTS: Injury data were collected during matches for 69 teams (48.3%) and training for 61 teams (42.7%). Injuries were primarily captured by athletic trainers in teams with medical staff, coaching staff and athletes in teams without medical staff. Common barriers in collecting and utilising injury data included limited funding for trained personnel and lack of time for medical staff to record data. Facilitating factors included clarification of the methods employed in recording and utilising injury data for teams with medical staff and the deployment of trained personnel to record injuries for teams without medical staff. CONCLUSIONS: Approximately half of the Japanese university teams collected injury data. Considering barriers and facilitators is crucial to facilitate the collection and utilisation of injury data.

      OBJECTIVE: Adequate conditioning results from various physical, environmental, and psychological factors in sports activities. In this study, we aimed to clarify the concurrence and relevance of injuries, psychological problems, and sleep disturbance in university football (soccer) players. Biomechanical characteristics and risk factors for those injuries were also investigated. METHODS: Overall, 1,084 university football players participated in this cross-sectional study using a web-based health history questionnaire. Assessments were made via the presence of injuries for physical problems, the Athlete Psychological Strain Questionnaire (APSQ) for psychologicalproblems, and the Athlete Sleep Screening Questionnaire (ASSQ) for sleep difficulties. RESULTS: There were 200 (19%) athletes with injuries; 413 (38%) of these were APSQ-positive, 246 (23%) were ASSQ-positive, and 468 (43%) athletes had no physical, psychological, or sleep problems. APSQ-positive respondents were significantly more likely to have a current injury than those who were APSQ-negative. No significant difference was observed between the number of ASSQ-positive and -negative respondents and current injuries. Those with sleep problems were significantly more likely to have psychological problems. CONCLUSION: More than 60% of university football players had one or more physical, psychological, or sleep problems. Players may have co-occurring problems, and it is important to address them for these athletes to reach peak performance.

      Injury prevention and health promotion among elite athletes are crucial to athletic success. Risk management requires the understanding and adjustment of physical, environmental, and psychological factors. Sleep status can be one of the essential factors for maintaining good health and preventing injury. The Athlete Sleep Screening Questionnaire (ASSQ) is expected to be an international standard for evaluating the sleep status of elite athletes. The 16 items ASSQ assess several sleep-related factors, including sleep difficulty, sleep-disordered breathing such as snoring and apnea, sleep and psychosomatic functioning during expeditions, chronotype, napping, caffeine intake, and electronic device use.

      A total of 158 male college soccer players responded the ASSQ-J and the Japanese version of the Pittsburgh Sleep Quality Index (PSQI-J). A factor analysis was conducted to validate the factor structure of the ASSQ-J. The internal consistency of ASSQ-J is assessed for validation. Pearson’s correlation coefficients and kappa statistic were calculated to determine if the ASSQ-J was significantly associated with PSQI-J respectively.

      Regarding the ASSQ-J-SDS, 22.4% (35 of 156) of the subjects in this study scored 8 or higher (moderate or higher), which was almost consistent with the results of a previous study on college athletes. It is clear that some Japanese male collegiate soccer players have sleep problems, as same as collegiate athletes around the world. Further research is needed for the validation of the ASSQ-J, the sleep status in a wider range of ages and sports are also investigated.

      Stability training is often carried out in the field of sports to improve performance. Appropriate loading is important in sports rehabilitation. Rehabilitation that ignores progressive characteristics can lead to a variety of reactions, including prolonged return to work and recurrence of injury. Therefore, it is desirable to objectively evaluate the load exerted by each training method. However, the degree of change in muscle activity in response to changes in foot ground contact height and stability when performing front bridge was unknown. Thirty-seven healthy subjects performed six different front bridges with varying foot height and instability. Muscle activity was measured and examined during implementation. Surface electromyography was used to measure the activity of the upper trapezius, lower trapezius, serratus anterior, rectus abdominis, external and internal abdominal oblique muscles, rectus femoris, and tibialis anterior. The rectus abdominis, external oblique abdominis, and internal oblique abdominis muscles showed significantly higher activity under conditions of instability of the foot ground contact surface. The upper trapezius, serratus anterior, external oblique abdominis, and tibialis anterior muscles showed significantly higher activity under conditions with a high foot ground contact surface. The upper trapezius, serratus anterior, external oblique abdominis, and tibialis anterior muscles required significantly higher muscle activity under high foot ground contact conditions. It was also suggested that the trunk muscles required significantly higher muscle activity under conditions where the foot ground contact surface was unstable.

      The Oslo Sports Trauma Research Center Questionnaire is an athletic epidemiological survey questionnaire targeting “all complaint injuries” (all problems with symptoms). The questionnaire includes questions regarding (1) participation, (2) modified training/competition, (3) performance, and (4) pain (symptoms) due to an injury at specific location or health problems at certain intervals. The prevalence and severity of problems are calculated to monitor changes in these parameters. This paper provides an overview of this questionnaire, its procedures, and major previous studies.

      BACKGROUND: Epidemiological data on sports injuries and illnesses depend on the surveillance methodology and the definition of the health problems. The effect of different surveillance methods on the data collection has been investigated for overuse injuries, but not for other health problems such as traumatic injuries and illnesses. PURPOSE: The purpose of this study was to investigate the new surveillance method developed by the Oslo Sports Trauma Research Center (OSTRC), which is based on any complaint definition (new method), to identify health problems compared with the traditional surveillance method, which is based on time loss definition. STUDY DESIGN: Descriptive epidemiology study. METHODS: A total of 62 Japanese athletes were prospectively followed-up for 18 weeks to assess differences in health problems identified by both new and traditional methods. Every week, the athletes completed the Japanese version of the OSTRC questionnaire (OSTRC-H2.​JP), whereas the teams' athletic trainers registered health problems with a time loss definition. The numbers of health problems identified via each surveillance method were calculated and compared with each other to assess any differences between their results. RESULTS: The average weekly response rate to the OSTRC-H2.​JP was 82.1% (95% CI, 79.8-84.3). This new method recorded 3.1 times more health problems (3.1 times more injuries and 2.8 times more illnesses) than the traditional method. The difference between both surveillance methods' counts was greater for overuse injuries (5.3 times) than for traumatic injuries (2.5 times). CONCLUSIONS: This study found that the new method captured more than three times as many health problems as the traditional method. In particular, the difference between both methods' counts was greater for overuse injuries than for traumatic injuries. LEVEL OF EVIDENCE: 2b.

      [Objective]To investigate the effects of acupuncture on sports activities of athletes
      [Methods]A total of 1,804 athletes were targeted. The method used was a collective survey. Questionnaires were administered after obtaining consent from the participants; online questionnaires were also provided. The questionnaire evaluated profile (sex, age); sensation immediately after acupuncture treatment, duration of stimulus sensation, stimulus intensity, stimulus sensation, and therapeutic effect; timing of acupuncture treatment; and questions related to acupuncture as to whether the acupuncture caused any adverse effects on play (movement) or showed any positive effects.
      [Results]In total, 1,525 (84.5%) valid responses were obtained. The survey analyzed 841 subjects (55.1%) who underwent acupuncture. The most common response after acupuncture treatment was that the subjects felt lighter and were able to move more easily; 43.9% of subjects gave this response. In addition, 10.6% of respondents said that they continued to feel pain similar to the sensation during acupuncture treatment and 7.7% said they felt weak. The most common response at 59.8% was that the sensation felt during acupuncture disappeared quickly after treatment was ended, 58.6% of subjects said that the sensation felt after acupuncture was optimal, and 48.3% responded that the sensation from treatment remained and a positive effect was observed. The most common timing for receiving acupuncture for 21.8% of subjects was after practice or a match:
      [Discussion and Conclusion]Acupuncture for athletes should be performed according to the guidelines, taking into account the competition schedule and type of competition and the appropriate amount of acupuncture stimulation, thereby preventing problems during competition.

      [Objective] The purpose of this cross-sectional questionnaire-based study is to investigate the challenges of adverse events during treatment by acupuncture and moxibustion to an athlete.
      [Methods] In total, 1,804 subjects, including athletes who participated in marathons and university athletes were enrolled in this study. The survey was conducted by distributing the questionnaire or via online questionnaire to the athletes who fit the criteria for the study. The questionnaires were collected after consent was received from the participants; online questionnaires were also collected. The questionnaire was examined for age, sex, and type of competition, purpose of the acupuncture treatment and the actual effects, and treated area, content of adverse event, number of times the subjects received acupuncture, and informed consent, and free description of adverse events.
      [Results] In total, 1,525 (84.5%) valid responses to the questionnaires were received. The survey analyzed 841 subjects (55.1%) who experienced acupuncture and moxibustion. The following responses about adverse events of acupuncture were obtained: "pain at time of needle insertion"; 17.0%, "subcutaneous-bleeding"; 10.1% and "pain and feeling of heaviness due to the needle": 10.0%, among others. For moxibustion, responses included "burns"; 5.9% and "malaise"; 5.8%, among others. In the free description, there were 17 descriptions of discomfort due to excessive stimulation and difficulty in movement during exercise. Of the questions regarding whether or not they received informed consent, 215 were received orally (25.6%), 34 were received in written form (4.0%), 99 were received both orally and in written form (11.8%).
      [Discussion and Conclusion] Acupuncture for athletes causes a certain rate of adverse events. It was suggested that guidelines for athletes to receive acupuncture safely and training and education for practitioners are important.

      [Background] Presenteeism, defined as the practice of sick workers who come to work, and whose work performance effectiveness has been reduced due to various signs and symptoms, causes a significant financial loss to companies. However, comprehensive and effective occupational health countermeasures have not yet been presented. Therefore, we report here the results of an interim analysis to determine whether an allowance for acupuncture treatment is beneficial for workers' presenteeism.
      [Methods] A four-week randomized intergroup comparative study was conducted on office workers who were aware of their presenteeism. Participants were allocated to either the control group, in which regular recommended presenteeism countermeasures for each workplace were implemented arbitrarily, or to the intervention group in which an allowance of up to 8,000 was given for acupuncture treatment, in addition to the usual arbitrary measures. The primary endpoint was the WHO-HPQ relative presenteeism score: a score lower than 1 indicates lower work performance; and it was analyzed with the "full analysis set" population.
      [Results] A total of 52 patients were assigned to the intervention group (n = 30) and the control group (n = 22). On average, the intervention group received acupuncture treatments 1.4 times for stiff neck and shoulders (67%), lower back pain (26%), depression (5%), and allergies (2%), and paid a total of 7,219; and 6,556 was paid as an expense allowance. As a result, the relative presenteeism score was 0.95 in the intervention group, compared to 0.91 in the control group, with a between-group difference of 0.04 (ES (r) = 0.22, P = 0.12).
      [Conclusions] With a total of up to 8,000 offered to office workers who were aware of their presenteeism, an acupuncture treatment allowance for a four-week period was provided 1.4 times on average. The results suggested that the treatment allowance would increase workers' performance efficiency by about 4% (equivalent to 19,691 per person) compared to those without it.

      Grant amount：\4290000 （ Direct Cost: \3300000 、 Indirect Cost：\990000 ）

      In the prevention of anterior cruciate ligament (ACL) injuries, the forefoot strike (FFS) could be a safer landing technique than the rearfoot strike (RFS) during cutting motions. In this study, we aimed to clarify the joint angles, ground reaction forces (GRFs), and muscle activity levels associated with FFS and RFS landings during 180°turns. Our results showed significant differences in the lower-limb angles, muscle activities, and GRFs between the FFS and RFS. These findings suggest that increased lateral gastrocnemius (GL) and semitendinosus (ST) activities during the FFS may prevent large amounts of tension from being placed on the ACL and thereby reduce the risk of injury. Furthermore, we investigated the injury rates before and after giving out the instructions regarding the forefoot landing movement. However, no significant difference was noted between the injury rates before and after instruction.

      The aim of this study was to investigate the relationship between the muscle actibity and the risk of anterior cruciate ligament (ACL) injury.
      At 50 ms prior to ground contact, BF, ST, and GL muscle activity was significantly greater during FFS cutting than during RFS cutting, and TA muscle activity was significantly greater during RFS cutting. At 50 ms after ground contact, BF and GL muscle activity was significantly greater during FFS cutting than during RFS cutting, while TA muscle activity was significantly lower during FFS cutting than during RFS cutting.
